The Inspiration and Innovation Behind Water Machines

Leila Conners interviews John Todd about the inspiration behind the water machine and how it works. John Todd was inspired by the interaction of the multitudes of life in the waters around Cape Cod, where he grew up. From that inspiration he invented the water machine, or the ecomachine...also known as a living machine. What the water machine does is use sunlight and a system of vats that contain plants, algae, bacteria, fish, snails...the multitudes...to cleanse polluted water. So in one end runs the polluted water, and out the other flows water free of metals, pollutants and is of the quality of drinking water.

Gravitricity - Ingenious Innovation in Grid Energy Storage

Charlie Blair, co-founder and managing director of Gravitricity walks us through the ingenious solution to energy grid storage based on weights and gravity. Gravitricity will become part of the world's toolbox of solutions when transitioning to 100% renewable energy.

Direct Air Capture Update with Christoph Gebald of Climeworks

Leila Conners discusses direct air capture (DAC) with Climeworks' Director and Founder, Christoph Gebald. Direct air capture pulls carbon out of the sky and turns it into feedstock for a multitude of applications including carbon negative fuels. DAC can also pull carbon out of the sky and permanently sequester it in the ground and Climeworks is doing that in Iceland.

Gravitricity:
A New Form of Renewable Energy Storage

As the world generates more and more electricity from intermittent renewable energy sources, there is a growing need for technologies which can capture and store energy during periods of low demand and release it rapidly when required.

Climeworks

Climeworks is in it for the long run and wants to do their part in reversing climate change. By climate relevant we mean capturing billions of tons of carbon dioxide from the air per year. According to the Intergovernmental Panel on Climate Change, humanity needs to remove around 10 billion tons of carbon dioxide from the air every year by mid-century. Direct air capture can play a significant role in achieving this. And we need you to make this happen! Together, we can inspire 1 billion people to remove carbon dioxide from the air. Together, we can build a climate-positive future for generations to come.
